What actually syncs
Both directions.
Every field that matters.

Three things eBay sellers told us
The pain isn't selling on eBay.
It's selling on eBay and everything else.
01
"The same unit just sold twice — once on eBay and once on Shopify. We refund, lose the buyer, take the defect."
Per-channel stock buffers and webhook-driven sync. The unit decrements everywhere within seconds of the eBay payment, not the next cron run.
4–9stypical sync latency
02
"Item specifics get out of sync. eBay flags the listing, we drop from Best Match, sales fall off a cliff."
One canonical product record. eBay's required and recommended item specifics are validated locally before push, then mirrored back if a marketplace clerk revises them.
1.4kspecifics validated per push
03
"The defect rate dashboard climbs and nobody knows until the seller-standards email lands."
eBay account-health pings land in the dashboard the moment they arrive. Defect events, late-shipment counts and unresolved-case totals are first-class widgets.
Liveaccount-health widgets
The listing flow
Every eBay field, in one form.
Validated before it leaves.
No more swivel-chair between your back office and the eBay seller hub. Variations, item specifics, store category, format and policies — handled locally and pushed through the Inventory API.

Inventory sync
A real-time stock count eBay can trust.
When a unit sells anywhere — Amazon, Shopify, your floor scanner, a phone order — the new quantity hits eBay through the Inventory API within seconds. Webhooks where the platform supports them, polling-with-a-pulse where it doesn't.
Per-channel buffer
Reserve 2 units for eBay until your reorder lands. Protects Top Rated status without manual hold-backs.
Multi-location ready
Three warehouses, one eBay store. We route by ship-from policy and quantity availability.
Throttle-aware
Updates batched into eBay's bulkUpdate envelope. Never trips the call limit, never queues for hours.
Reservations during pick
Stock decrements at allocation, not at label. No double-sells while orders sit in the cart.

Orders & fulfilment
From order paid to tracking number.
One pipeline, four steps.
Every eBay order flows through the same fulfilment pipeline as Amazon, Shopify and Walmart — so your warehouse staff don't learn a new app per channel.
01
Paid order arrives
Trading API · OrderPaid
Webhook lands. Buyer, address, fees, item specifics and any custom buyer message — all captured against the canonical order.
02
Allocated to a warehouse
Engine · routing rules
Picks the location that satisfies all lines with the fewest splits, respects ship-from policy, and never crosses a Top Rated handling-time SLA.
03
Picked, packed, labelled
Floor · pick + carrier
Lands on a wave pick list. Carrier rates compared, label printed, the eBay order marked picked.
04
Tracking back to eBay
Fulfilment API · shippingFulfilment
Tracking number, carrier code and time-of-shipment posted back. Counts toward the Top Rated on-time metric automatically.

Asked before every eBay seller switches
Six questions.
Honest answers.
Yes. Motors-category listings carry the full compatibility table — make, model, trim, engine, year — pushed through the Inventory API's compatibility field. Category-required specifics are validated locally before push.
No per-account fee. The Growth plan covers up to two stores; Scale is unlimited. Each account is its own inbox, but the canonical catalogue underneath is one record set.
Once a bid is placed, eBay locks most listing fields. We mirror that lock — the form goes read-only for fields eBay would reject, with a tooltip explaining why.
An inbound webhook lands within seconds. The revision is mirrored back into the canonical record and flagged in the activity log. Conflicts with a local edit are surfaced for review, never silently overwritten.
Yes — both legacy GSP and the newer eIS. You set the policy once; eligible orders route through it and the tracking handoff counts toward your Top Rated on-time metric.
No. The first sync matches your live offers to your catalogue by SKU, then MPN, then a fuzzy title match for review. Matched listings stay the same listing on eBay — we just attach our record.
